1.2 Updates to the Observer's Handbook

This version of the handbook is applicable to for Cycle 5. Between the time of writing and the start of Cycle 5 observations, the analysis of data obtained as part of ongoing Instrument Commissioning work for HAWC+ are likely to provide more empirical information regarding instrument performance. The Observer's Handbook will be updated as necessary and the list of changes will be included at the beginning of the document. Critical updates will also be published on the Cycle 5 web page. Any information that supersedes what is given in this document will be explicitly indicated.
